SPECIFICATION forming part of Letters Patent No. 559,283, dated April 28, 1896. Application nad Jimmy 13,1896. sena No. 576,009. (No model.)

To all whom, it may concern:

Be it known that I, JAMES R. HARPER, residing at Schochoh, in the county of Logan and State of Kentucky, have invented a new and Improved XVheat-Drill, of which the following is a specification,

My inventionis in the nature of acombined runner and plow drilling machine; and it has for its object to provide a machine of Io this character of a simple and economical construction, in which the several parts can be quickly and easily manipulated to set the same in position to operate either as a runner or plow drill. i

r 5 My invention also has for its object to provide a machine of this character in which the runner and plow devices are oompactly combined, whereby they canbe the more readily adjusted, and whereby they will the more efzo fectively serve for their intended purposes.

Vith other objects in "view, which will hereinafter be referred to, the invention consists in the peculiar combination and novel arrangement of parts, first described in dez5 tail, and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure l is a perspective View of a drillingmachine constructed in accordance with my 3o invention. Fig. 2 is a longitudinal section of one of the combined runner and plow drills and the operating devices therefor, the same being adjusted as a runner-drill. Fig. 3 is a top plan View of the parts shown in Fig. 2.

3 5 Fig. 4 is a longitudinal section showing the drill arranged as a plow-drill. Fig. 5 is a horizontal section on the line 5 5 of Fig. 2.

Fig. G is a detail perspective View of the latch device hereinafter referred to.

In Fig. l, I have shown a drilling-machine having a number of drills A, constructed in accordance with my invention, and a grainbox B, common to all the drills, having the usual flexible or rubber-hose tubes C, which lead the grain from the box B to the drills.

As the construction of all the drill inembers and the means for setting the same in an operative position are the same, I shall describe but one drill and operating device therefor in detail.

Referring new more particularly to Figs. 2

and 4 of the drawings, D indicates the main frame of the machine, and E a drive or supporting wheel. The front end of the frame D has pendent ears d, in which is held a cross-rod e, upon which is pivotally hung the front end f of the upper bar F' of the runnerframe, the rear end of such bar F' being bifurcated, as at f', and connected to a boot portion f2, the lower end of which .is joined 6o to the rear spread ends f3 f3 of the runner F, the front end of which connects with the bar F', as clearly shown.

Projected upward from the bar E' is a connecting-rod G, pivoted at its lower end tothe bar F', and having its upper end slotted, as at g, to receive the cross-pin h of a crank-arm H, projected from a rock-bar I, journaled in the top of the frame D, and having at one end an operating-lever J, having the usual 7o spring-pawl or detent devices j to engage the segmental rack member j', the handle portion. of the lever having a pivoted link J', adapted to engage and hold the detent devices j released from the rack j', for a purpose pres- 75 ently explained.

K indicates a coiled spring disposed about the upper end of the connecting-rod Gr, between the end of arm 7L and a cross-pin or stop g', the purpose of which will also pres- 8o ently appear.

L indicates a boot member or chute held for vertical movement in the boot portion. f2 of the runner, the lower end of which has a discharge-opening M and a front plow member N, its rear side having an apertured lug member L', which projects through an elongated slot f5 in a pendent extension f6 of the boot portion f2, as clearly shown in Figs.. and 4., such lugbein g connected with the cross- 9o bar o of the bail or bracket rod O, the front end of which is pivotally joined to an ear f7, held pendent on the bar F', such rod O serving to form a brace to steady the plow end of the boot or feed-chute L.

llhe front end of the boot portion f2 is slotted vertically, as indicated by fg, while the boot L has a lug P, with which a latch member R is adapted to engage and which will serve,

j when properly adjusted, to keep the member 1oz L in its elevated or lowered position.

The latch Ris pivoted to the bar F' and has an upper toe portion r, which is adapted, when the parts are in the position shown in Fig. 2, to engage the under edge of the lug P and hold the boot L and plow elevated. The lower end of the latch R is also formed into a toe member o", which is adapted to project through the slot fg, and when the parts are in the position shown in Fig. 4 such member 7" will engage the upper edge of lug P and hold the boot L, with the plow, down in engagement with the ground.

The latch R has a crank portion or ear R', to which is connected one end of a pitmanrod S, the front end of which connects with a crank member on a rack-rod T, j ournaled in the pendent ears d, one end of which has a crank member t', to which is pivotally connected one end of a pitman-rod U, the other end of which is pivotally joined to an operating-lever V, pivoted to the main frame D, and having the usual springwactuated detent devices e, which are adapted to engage the segmental rack lV, as shown.

X indicates a rock-shaft journaled on top of the main frame I), which has an upwardlyextending lever f', having the usual detent devices to engage the rack Y aud provided with a crank member having a cross-pin passed through the slotted end z ot' a lift member Z, secured to the front side of the upper end of the grain chute or boot L, such end Z also having a coiled spring z' disposed between the end of crank member x' and a cross-pin z2, as clearly shown.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. In a machine as described, the combination with the main frame, of a runner pivotally connected at the front end to the frame having at the rear a boot or pocket member, a vertically-adjustable boot held in the runner-boot having a plow at its lower end and means for adjusting such plow and boot, vertically holding the plow-boot locked to its raised position substantially as shown and described.

2. In a machine as described, the combination with the main frame and the seed-box of a vertically-adjustable boot having a plow at the lower end, a runner pivotally connected at the front end to the frame having at the rear a boot portion vfitted over the plow-boot, a lever mechanism i'or raising the rear end of the runner substantially as shown and described.

3. In' a machine as described, the combination with the frame, the runner, a latch member carried thereby, hand-operated lever devices for operating same, a plowcarrying boot having a locked member adapted tobe engaged by the latch, a lever mechanism for raising the plow-boot and the runner independently of each other substantially as shown and described.
